Tunneling of photons in frustrated total internal reflection has been studied
in the time domain with single-cycle femtosecond pulses. It is seen that both
the phase and energy of the pulse travel faster than the speed of light in
vacuum. Theoretical analysis of the experiments shows that the time-response
function for electromagn |
